Abstract
Crosslinkable liquid composition based on organic isocyanates and epoxy compounds, comprising the following components: PA1 (A) an organic polyisocyanate; PA1 (B) a polyepoxide or mixture of a polyepoxide and a monoepoxide; and PA1 (C) a catalyst constituted by at least one cyanoderivative containing a quaternary nitrogen atom, which composition can be polymerized at temperatures of 40.degree. C. or higher, by a process comprising exposure thereof to a non-ionizing electromagnetic radiation having a frequency comprised in the microwave range of frequencies, to obtain a solid material endowed with an excellent combination of physical, chemical and mechanical properties.
